The chemical dosimeter that measures the UV irradiation dose promptly and handily for UV flow device was examined. The fluorescent measurement and the optical whitening agent were used to do under the high transparency condition similar as drinking water. The reaction promotion using the photocatalyst and the wavelength dependency of disinfection efficiency assuming to apply the polychromatic lamp were examined. It was observed that 0ptical whitening agent FBA-1 were neither the concentration nor the UV intensity dependency, and first order reaction material withno active moiety, and enhancement by photocatalyst wasn’t confirmed in high transparentcondition. In addition, the simulation of the UV dose distribution that assumed thediffusion light model and the laminar flow model in the flow device was implemented. And the results of simulation and the outcome of an experimental results of the bio dosimeter and FBA-1 dosimeter were within about 20 percent in error margin. Moreover, it was observed that the disinfection efficiency of short wavelength light was higher. However, it was thought to be able to apply this fluorescent-chemical dosimeter also to the polychromatic lamp because the influence of short wavelength was a little considering output spectrum of the lamp.

检查了迅速和方便地用于紫外线流量装置的紫外线辐射剂量的化学剂量表。荧光测量和光学美白剂用于在与饮用水相似的高透明条件下进行。研究了使用光催化剂和假设应用多色灯的消毒效率的波长依赖性促进的反应。据观察，0义美白剂FBA-1既不是浓度也不是UV强度的依赖性，也不是没有活性部分的一阶反应材料，并且在高透明条件下没有证实光催化剂的增强。另外，实现了假定扩散光模型和流动设备中层流模型的紫外剂量分布的模拟。以及模拟的结果以及生物剂量计和FBA-1剂量计的实验结果的结果在误差边缘约20％之内。此外，观察到短波长光的消毒效率更高。但是，人们认为它也能够将这种荧光化学剂量仪也施加到多色灯中，因为短波长的影响有点考虑到灯的输出频谱。
